HERMAN HERMANSEN, OF-BAYBRIDGE, OHIO.

DUST-COLLECTOR.

Specification of Letters Patent.

Patented June 2 7, 1916.

Application filed April 20, 1916. Serial No. 92,482.

v do declare the following to be a full, clear,

fill

and exact description of the invention, such as will enable others skilled in the art to which it appertains to make andA use the same.,-

My invention relates to improvements in dust collecting devices for use in connection with numerous types of flues through which dust laden air or gases travel, the object being to provide a simply constructed yet eiliient arrangement of parts which will combine the forces of momentum and gravity in separating particles of dust and the like from the draft in which they are carried.

With this general object in View', the invention resides in certain novel features of construction and in unique combinations of parts to be hereinafter fully described and claimed, the descriptive matter being supplemented by the accompanying drawing which constitutes a part of this application and in which:

Figure 1 is a side eleyation of the improved dust collector; Fig. 2 is a vertical section thereof; and, Fig. 3 is a horizontal section as viewed on the plane of the line a--e or Fig. a

In specifically describing the structure shown in the drawing above vbrie-[ly described, similar characters will be placed on corresponding parts throughout the severa-l views and reference will be herein made to the numerous elements by their respective indices. To this end, the numeral 1 desi: iates an upright flue section which in cases is adapted to be secured to the end of a stack or flue, but if found .Y zble, it maywell be an integral part of ne s'wck. ln thc embodiment of the invention illustrated, the lower end of the flue sflction l is provided with an angle metal band '2 .by means of which it may be secured to a stack, while the upper end of said section is bound by a metal strap 3.

A cylindrical casing l surrounds the section 1 and is supported thereon by inclined bars secured at their upper ends to the strap 3 by riveting or the like, the lowe.A ends of said bars being similarly fastened to the casing 4f. The lower end of the cas ing terminates in a steeply inclined plane and is closed by a bottom 6 having therethroughan opening 7 through which the flue section 1 passes, an angle metal collar 8 preferably surrounding said section at this point, the collar being riveted, bolted or otherwise secured to the bottom 6. At its eX- treme lower end,'that is at the lower eXtremity of the bottom G, the casing 4 is provided with a dust outlet which is preferably i in the form of a nipple 9 having thereon an angle metal collar 10 for securing it to a pipe which may be used to convey the collected dust and the like from the casing l to any desirable point.

Formed through the circular wall of the casing 4; and spaced a considerable distance below the top 11 of said casing is a plurality of circumferentially spaced air or gas outlets 12, these outlets being also disposed below the discharge end of the flue section 1 which end is preferably in close'proximity to the aforesaid top 11. An annular baffle plate 13 is secured at its upper edge by riveting -or otherwise to the wall of the casing Il above the outlets 19., said plate inclining downwardly and inwardly throughout its circumference and extending to or below the plane in which the lower edges of said outlets .12 are disposed. The balile plate 13 thus prevents the direct passage of air or gases from the flue section 1 through the outlets 1Q, causing the same to pass downwardly on the inner side of said plate 13 and 'then laterally beneath the latter to said outletsl 2'. 1n traveling downwardly in this manner, the particles of dust and the like will gain considerable momentum'and the latter will act simultaneously with gravity to prevent such particles from turning laterally with the air or gas current. The result is that the particles in question will continue on a downward path and will thus be separated from thc draft in which they have been carried to the upper end of the flue or stack. These particles will fall upon the inclined bottom' C ant will leave the casing 4: through the outlet 9 thereof.

Preferably used in addition to the parts above described, Ais a plurality of hoods or cowls lll disposed over the numerous air or gas outlets 12 to prevent the entrance of rain, snow and the like. These cowls'and the other parts of the invention described,

- however, will not noticeably retard the draft of the iue or stack ,to whichthe device is applied in view of the fact that the casing 4 in cross section is several times the area 5 of the stack or flue.V

readily understood without requiring a more extended'explanation, but in conclusion, I' will state that although lcertain specific def tails have been shown and described for' accomplishing probably the best' results,

i5 numerous changes-may be made within the scope of .the 'invention as claimed, without sacrificing any of the main features thereof.'

I claim! y y A .dust collector comprising a iue through which an upward 'draft 'of' dust-laden air or gas is. adapted to travel', a 4cylindrical casing surroundin the upper end of said flue and having a c os'ed top and bottom, the

v latter being steeply inclined and having at itslower end a dust outlet, metal straps secured to the upper end of the flue at one end and to the wall of said casing at their other ends,said wall having a plurality of circumferentially spaced air or gas outlets disposed below the. upper' end of the flue, hoods'on the exterior of the casing and eX- tending over said air or gas outlets, and an annular baille plate in said casing secured at its upper edge to the wall of the latter above said air or gasoutlets, said baille plate inclining downwardly and inwardly and terminating in or below the plane of the lower edges of said outlets, said baille plate lserving to cause the air or gas to travel downwardly and then laterally, such ldownward travel serving to impart momentn to the particles of dust and the like in said air or gas, this momentum acting simultaneously with gravity to .separate the aforesaid particles from the draft in 'whchlthey have been carried. l,

In .testimony whereof I have hereunto set my hand in' presence of two subscribing witnesses.
